What is the dramatic prologue in Oedipus King?

In the dramatic prologue of Sophocles' "Oedipus Rex" (also known as "Oedipus the King"), the play opens with a scene depicting a plague devastating the city of Thebes. The people of Thebes are suffering greatly, and they have come to Oedipus, their king, for help. Oedipus, who is shown as being greatly concerned about his people's welfare, has already sent his brother-in-law, Creon, to the oracle of Apollo at Delphi to seek guidance.

As the prologue unfolds, Oedipus addresses his people, expressing his determination to find the cause of the plague and punish those responsible. He passionately vows to leave no stone unturned in his pursuit of justice, even if it means uncovering long-buried secrets.

In this dramatic prologue, Sophocles establishes the dire situation in Thebes, Oedipus's strong sense of duty, and the urgency of solving the mystery surrounding the plague. The audience is immediately drawn into the conflict and the complex events that will follow as Oedipus embarks on a journey of self-discovery that ultimately leads to a tragic revelation about his own past.
